This generation of consoles seems to be winding, and fans will probably play on brand new systems soon. This has led to a lot of speculation about what the next console generation will look like internally. Now Marc-André Jutras, a gaming industry veteran with more than 15 years of experience under his belt, has stated what he thinks [Xbox 360] and next Xbox PS5 Xbox will look like power-wise .
Recently, Jutras claimed that the next generation of systems will not be as big of a leap as many believe it will be. Instead of the fleshy 16GB of RAM that someone has speculated on the consoles, Jutras thinks it's likely to be a modest 8-12 GB, so many games don't use as much RAM. Jutras also believes that the PS5 and the next Xbox can use Ryzen 2600 processors, or something similar to them, due to stability, core numbers and relatively low cost.
However, the next generation of consoles will probably see a huge increase in VRAM, according to Jutras, with the systems likely to boast 8 GB of dedicated VRAM to support 4K games with a reasonable frame profile as opposed to the unified memory of the systems in day use. It is also worth noting that the next Xbox is rumored to have multiple levels and price points, and it is unclear what level will include specifications like these.
Jutras' predictions are in stark contrast to those made by industrialist Michael Pachter a few days ago when he predicted that the consoles would support 240K FPS games. However, Jutra's requirements are much more sensible, as gaming at a 4K resolution with 240 FPS is something that even the highest PCs still can't achieve, and any system that will likely cost thousands of dollars.
If players choose to believe Jutras, Pachter, or draw their own conclusions, are up to them. Nevertheless, it may not be too much longer before they have a final idea of the type of console hardware to come. The PS5 and Xbox are both rumored to be announced in 2019, with launches possibly happening once in 2020. What the consoles will look like is still some guess, though almost all drastic hardware changes are imaginable. this point.
 PS5 and next Xbox have not yet been officially disclosed.
